Single-Chip Si534xH Clock Family Provides High-Performance,
Frequency-Flexible Timing Solution for 100G/400G Transceivers
AUSTIN, Texas--(BUSINESS WIRE)--
Silicon
Labs (NASDAQ: SLAB) has introduced a family of jitter-attenuating
clocks that simplifies 100G/400G coherent optical line card and module
design by providing a high-frequency, flexible clocking solution that
significantly reduces system-level cost and complexity. Silicon Labs'
new Si534xH coherent optical clocks replace discrete timing solutions
that rely on expensive, large-footprint voltage-controlled SAW
oscillators (VCSOs) to provide low-jitter reference timing for data
converters. Unlike VCSOs that support single, fixed frequencies, the new
Si534xH clocks operate over a wide frequency range, supporting
frequencies up to 2.7 GHz without the need to change bill-of-material
(BOM) components.

Silicon Labs Si534xH Clock Family: High-Performance Timing Solution for Coherent Optical Networks (Photo: Business Wire)
The Si5344H and Si5342H clocks combine best-in-class frequency
flexibility with unparalleled jitter performance of 50 fs RMS. The
devices simplify component sourcing, replacing multiple custom,
long-lead time VCSOs with a clock IC solution available with short,
two-week lead times. Featuring a jitter-attenuating PLL, high-frequency
output drivers, fractional frequency synthesis and digitally controlled
oscillator (DCO) technology, the Si534xH family provides all the
clocking functions required for coherent optical transceiver
applications while enabling 40 percent smaller footprint and 40 percent
lower power than competing solutions.

clocks including data sheets, supporting documentation and development

One of the largest growth drivers in the communications market is the
industry's transition from 10G to 100G in metro area networks and data
center interconnect (DCI). Coherent optics is an enabling technology for
100G and 400G applications because it allows service providers to send
more data over existing optical fiber, minimizing the cost and
complexity of network upgrades for bandwidth expansion. Current timing
solutions for coherent optics are not optimized for cost or size,
requiring a diverse mix of VCSOs, clock generators and discrete
components.
Silicon Labs' Si534xH clocks are purpose-built to address the timing
requirements of 100G/400G coherent optics. In addition to supporting the
ultra-high frequency synthesis necessary for clocking optical
transceiver data converters, the Si534xH clocks combine Silicon Labs'
proven DSPLL® jitter attenuation technology and MultiSynth low-jitter
fractional frequency synthesis technology to deliver an elegant,
easy-to-use, single-chip solution. All 100G/400G transmitter or receiver
clocks can be generated by a single device, minimizing BOM cost and
complexity by eliminating the need for numerous discrete components.
"To meet demands for increasing bandwidth, service providers require
100G/400G coherent designs that enable higher line card port density and
lower cost-per-bit than legacy solutions," said James Wilson, senior
marketing director for timing products at Silicon Labs. "Silicon Labs'
Si534xH clocks provide the high-frequency clock synthesis, jitter
attenuation and stringent phase noise required by coherent optical
applications at significantly smaller footprint and lower power than
traditional VCSO-based solutions."
Silicon Labs supports coherent clock development with ClockBuilder Pro,
an easy-to-use software tool that simplifies clock tree design, device
configuration and detailed performance evaluation. The tool can be used
in standalone mode to generate device configuration files or to directly
control a Si534xH device on an evaluation board. ClockBuilder Pro can
also be used to create factory-customized versions of Silicon Labs'
jitter attenuators and clock generators individually tailored to meet
each customer's unique timing requirements.
